I’m sure you guys heard about a little get-together last weekend called PAX. The guys from Penny Arcade showed the world (yet again) that there’s life after E3. In honor of the event, the Harmonix crew put together a three-pack from some of the performers from the show.

Jonathan Coulton “Skullcrusher Mountain”

MC Frontalot “Livin’ on the Corner of Dude and Catastrophe”

Darkest of the Hillside Thickets “Shhh….”

All three tracks are going for $.99 each starting today, and are master recordings. What’s unusual about this week’s DLC is that all of the monies from your purchases will go to the Child’s Play charity which helps out sick children who are in hospitals during the holidays. It’s a good cause, and the music is great, so download them already!
